Pronunciation: [sˈa͡ɪd ˈɪʃuː] (IPA) 
The spelling of the word "side issue" can be explained using IPA phonetic transcription. The first syllable "side" is pronounced as /saɪd/ with a long "i" sound, followed by a voiced "d" sound. The second syllable "issue" is pronounced as /ˈɪʃuː/ with a short "i" sound, followed by a voiceless "sh" sound and a long "u" sound. Together, the word means a minor or secondary issue that is not directly related to the main subject.
A side issue refers to a secondary or ancillary matter that is relatively less important or unrelated to the main or central focus of a discussion, argument, or event. It is a topic or concern that is not the primary subject being addressed, but arises incidentally and diverts attention from the main issue at hand. Side issues are typically seen as peripheral to the main agenda or purpose, often arising as tangents or digressions.
These auxiliary matters may be brought up unintentionally or intentionally in attempts to lead away from the central topic of discussion. Side issues are often regarded as distractions or detractions from the primary subject, as they deviate from the main point under scrutiny and may hinder progress in reaching a resolution or decision.
The term "side issue" can be applied across various contexts, including academic discussions, political debates, legal proceedings, and everyday conversations. Its purpose is to highlight a diversion of focus or attention away from the primary objective or main argument. By identifying and recognizing side issues, individuals or groups can better discern the crucial points to address or decide upon, allowing for higher efficiency and clarity in discussions and decision-making processes.
The term "side issue" is derived from the combination of two words: "side" and "issue".
The word "side" originated from the Old English word "sīde", which referred to the division or part of something. Over time, it evolved to mean the lateral or outer surface of an object or area. It can also be used figuratively to denote a perspective or viewpoint.
The term "issue" comes from the Latin word "issūs", which meant "to go out" or "to emerge". In English, "issue" initially referred to the act of producing something or releasing it into circulation. Eventually, it expanded to encompass a broader sense of significant topics, discussions, or debates.
When combined into "side issue", the term suggests a matter or topic that is of secondary importance or less significance compared to the main or central issue.
